Metal to Metal seated Ball valve is a valve in which the opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid adjustment and control.
The characteristics of the ball valve:
1. Wear-resistant;
As the valve core of the metal to metal seated ball valve is spray-welded alloy steel, the sealing ring is made of alloy steel surfacing, so the hard sealing ball valve will not produce too much wear when opening and closing. (Its hardness coefficient is 65-70):
2. The sealing performance is good
As the sealing of the metal to metal seated ball valve is manually ground, it can not be used until the valve core and the sealing ring are in agreement. Therefore, its sealing performance is reliable.
3. The switch is light;
Since the bottom of the sealing ring of the metal to metal seated ball valve uses a spring to make the sealing ring and the valve core tightly hug together, the switch is very light when the external force exceeds the preload of the spring.
4. Long service life
It has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily life.
